What is This?
A QR (Quick Response) code is a two-dimensional barcode readable by smartphones and dedicated scanners. QR codes encode data like URLs, text, WiFi credentials, or vCard contact information in a square grid of black and white modules. Modern smartphones can scan QR codes using the built-in camera.

- Enter the data (website URL, WiFi password, contact details, etc.)
- Choose size (200x200 to 2000x2000 pixels for print)
- Select error correction level (L, M, Q, H for different damage tolerance)
- Customize colors, add logo, or adjust corner style (optional)
- Download as PNG or SVG file
- Test QR code with multiple scanner apps before mass deployment

Event Check-In
Generate unique QR codes for event tickets. Attendees show QR codes at entrance for fast scanning and check-in. Track attendance, prevent duplicate entry, and gather analytics. Integrate with ticketing platforms like Eventbrite.
Product Packaging

Tips & Tricks
- Test before printing: Scan with multiple apps (iPhone Camera, Android Camera, dedicated QR readers) to ensure compatibility
- High error correction for logos: Use H level (30% correction) when adding logos to QR codes to maintain scannability
- Sufficient contrast: Ensure dark-on-light contrast for reliable scanning. Avoid low contrast color combinations
- Minimum size: Print QR codes at least 2cm x 2cm (0.8" x 0.8"). Larger is better for long-distance scanning
- Short URLs: Use URL shorteners for QR codes - less data means simpler, easier-to-scan codes
- Add call-to-action: Include text like "Scan for Menu" to encourage scanning
- Dynamic QR codes: Use QR code services with redirect capability to change destinations without reprinting
